PIPE-HOLDING KEY.

Application filed May 1,

T 0 all whom it ma y concern Be it known that I, RICHARD WEBB BUR- XETT.a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a certain new and usefulImprovement in Pipe-Holding Keys, of which the following is a full,clear. concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

This invention relates to improvements in pipe holding keys.

The object of the invention is to provide a key for holding train pipesor other pipes in brackets, which key is so arranged and constructed asto be readilyinserted in the slots usually provided therefor so that thekey wedges the pipe tightly in position and the key has a bendabletongue to secure it in position and a blunt section to facilitate itsremoval by the use of a hammer or other suitable tool.

In the drawing forming a part of this specification, Figure 1 is anelevational view of a diaphragm or cross sill of a car showmg myimprovements in connection therewith for supporting a train pipe. Fig. 2is a vertical section of the structure illustrated in Fig. 1 and takenon the line 22 thereof. Fig. 3 is an enlarged sectional view takensubstantially on the line 3-3 of Fig. 1 and looking in the direction ofthe arrows shown. Fig. 4 is a vertical sectional view of anotherembodiment of my improvement showing the method of securing the bracketto the side of a sill of a car. Fig. 5 is a side elevation of thestructure illustrated in Fig. 4, looking from left to right. Fig. 6shows another embodiment of my invention applied to an angle cock holderand taken on the r line 6-6 of Fig. 7. And Fig. 7 is a view of thestructure illustrated in Fig. 6 and taken at right angles thereto.

Referring now to Fi 1, 2 and 3, 10 de notes a diaphragm, nee 1e beam orcross sill of a car, the same being of channel form and to which isattached my improved anchor. As shown, the pipe anchor comprises abracket member or casting 11 having upper horizontally extending an es12-12 by which the bracket is rivete or otherwise secured to the lowerflange ofthe channel 10. The bracket casting 11 is provided with a pairof depending, spaced arms 1313 between which is formed a curved seat 14for the train pipe 15 to be seated in. As will be Bpecifloation ofLetters Eatent.

apparent, the train pipe 15 can be inserted or removed after the anchoris in position. To secure the pipe in position, the depending arms 1313are provided near their lower ends, with alined slots or perforations1616 through which is extended a key 17 tapered in the direction of itslength as appears most clearly from Fig. 1. In the construction shown inFigs. '1 and 2. I show. a block 18 grooved on its under side asindicated at 19 to receive the key 17 and provided with a curved seat 20on its upper face to fit the pipe 15. Said block 18 may be corrugatedcircumferentially of the pipe or otherwise roughened to prevent the pipefrom slipping lengthwise.

Referring now more particularly to the key 17, the same is shown asprovided with a slot or cut 21 at its smaller end,said cut 21 beingperpendicular to the sides of the key and extended to a point within therecess or openinglG in the adjacent arm 13, when the key is in operativeposition. The smaller or advance end of the key 17 is thus divided intotwo tongues or tangs 22 and 23. One of these tangs, is left with abluntend 24 which, as clearly appears in Figs. 1 and 3, is extendedbeyond the outer face of the adj acent arm 13, when the key is inoperative position. The .other tang 23 is tapered in thickness asappears from Fig. 3, from a point commencing at the inner end of theslot 21. The tang 23 is made preferably longer than the blunt tan 24 andis adapted to be bent around the a jacent arm 13, as appears from Fig. 3and in this connection, it will be noted that the taper, commencing atthe point indicated, facilitates this operation.

By employing a locking key of the structure above described, I havefound that the same may be readily secured in place by means of ahammer. the hammer being first employedto drive the key into positionand then to bend the tang 23 over the adjacent portion of the arm 13. Toremove the key, a hammer or other suitable tool is employed and the keyis struck on the blunt end 24:. This construction is particularly usefulin cars where the workmen are compelled to operate in cramped quarters,as has been proven by actual experience.

Referring now to the construction illustrated in Figs. 4 and 5, thebracket 11 is constructed so as to have the arms 113113 thereof extendhorizontally and t e bracket secured to the side or web of the channel110. In this construction also, a block 118 is employed with akey 117similar to the key used in thestructure illustrated in Fig. 1 andheretofore described in detail.

In the construction illustrated in Figs. 6 and 7, the anchor bracket 211is of substantially U-shape similar to the anchor bracket shown in Fig.1 and having its arms 213-213 extended downwardly. In this construction,the anchor bracket is also adapted to serve as aholder for an angle cockand for this purpose is provided with an outwardly extended, integrallug 10 adapted to engage one face of the hexagonal nut ll of the anglecock and when the latter is in its proper position. The train pipe isheld in position by .a key 217 similar to the key 17, as will beunderstood. As is apparent from the drawing, the lug *0 will preventturning of the angle cock in either direction, after the pipe is placedin position and tightly secured by the key 17. The arrangement isexceedingly simple and cheap to manufacture and efiiciently per-' formsall the functions necessary for holding the angle cock in place,

From the preceding description, it will 'be seen that the arrangementwhich I have provided, permits of the easy locking in place of the keyand removal thereof and reuse of the key which will preferably be madeof malleable iron.

I claim:

1. As an article of manufacture, a key adapted for use with pipe anchorsand the like-having alined slots to receive the key, said key beingtapered in width in the direction of its length so as to adapt the keyfor wedging a pipe in position, said key being slotted lengthwise at itsnarrower end to thereby form two tangs, one of said tangs being shorterthan the other and having a blunt end, the longer tang being bendableand adapted to be readily bent by striking the same with a hammer orequivalent tool whele it projects beyond the blunt ended tang, the bluntended tang being provided to facilitate removal of the key by striking ahammer or other suitable tool thereagainst.

2. As an article of manufacture, a key adapted for use with a ipe anchorbracket having slots to receive t 1e key, said key be ing tapered inwidth in the direction of its length and formed at its narrower end withtwo distinct portions separated by a longitudinally extending slot inthe key,,sa1d slot extending normally within the adjacent slot of thehanger bracket when the key is in place, one of said portions having ablunt end and the other portion being tapered in thickness so as toadapt it to be bent around an adjacent portion of the bracket.

In witness thatI claim the foregoing I have hereunto subscribed my namethis 27th day of April 1916.

RICHARD WEBB BURNETT.
